Danny Phantom

Paulina is absent in this episode. This is the first episode since her first appearance in which she plays no part.

The name of the episode applies to what Skulker said in the opener about Danny, "One of a kind" because he's the only known halfa so far in the series.

Cable Episode Info: A ghost hunter sets his sights on Danny.

This marks the first time that someone other than Danny defeats an opponent.

When Tucker releases the ghosts from the Fenton Thermos all of the ghosts (except for Box Ghost) are wearing a suit and tie, a reference to an old joke that businessmen and lawyers are evil demonic creatures.

Apparently, human-designed PDAs are compatible with ghostly ecto-skeletons.

This is the first episode to begin with Danny already in ghost mode.

Look Hard: On the cover of Genius Magazine, Maddie and Danny are in front, but Jack is behind Delilah with his face only showing. The label of the cover says "HE is a SHE: Genius Child of Genius Woman Discovers Gorilla Male Actually a Female."

We learn that Mr. Lancer is also Danny's biology teacher, as well as his English teacher.

This marks the first time that we see Danny shivering when his ghost sense goes off.

According to Tucker's PDA, Casper High officially ends at 3:10 PM.

Look Hard: The following was the schedule on Tucker's PDA, right before Skulker put it into his ecto-skeleton: 12:00 - Eat Lunch 1:00 - Library 1:30 - Meet Sam 2:00 - Gym Class 3:10 - Go Home

Look Hard: On the first sentence on Danny's "D" biology test, the word "antidisestablishmentarianism" is there, but it has no connection to biology.

Skulker's weapons and gadgets that are featured in this episode are: 1) Ghost-detecting goggles. 2) Ecto-web shooter. 3) Ecto-goo launcher. 4) Net blaster. 5) Hologram projector. 6) Ghost portal activator. 7) Ghost handcuff projector. 8) Jet pack. 9) Green link chain producer. 10) Neck brace producer. 11) Blue ecto-jelly materializer. 12) Armor polisher. 13) Bow and arrow.

Opener: Danny is fighting The Box Ghost near a dock. After ranting about who he is, The Box Ghost throws a bunch of items at Danny, but Danny phases through. Tucker and Sam bust in and Tucker traps The Box Ghost in the Fenton Thermos. Danny tells them to be more focused as sidekicks. Tucker then drops the thermos and all the ghosts inside it escape, including The Box Ghost, who once again rants. Meanwhile, the Ghost Zone's greatest hunter, Skulker, is spying on Danny, and he plans on putting him in a cage.

According to Skulker's analysis using Tucker's PDA, Dash is an ordinary child destined for an ordinary life after high school. This analysis regarding Dash's future was first hinted by Dash in "Mystery Meat."

This is the first time that Tucker has captured a ghost using the Fenton Thermos.

According to the Ghost Gabber, the word "Boo" actually translates to, "I am a ghost, fear me."

Apparently, Jazz has an obsession to prove to the world that she has normal parents instead of "a bunch of ghost-hunting freaks."

Look Hard: There are some posters of rockets on the walls of Danny's room. He also had a model rocket that he built. These all seem to reflect to his desire to become an astronaut, which was mentioned in "Mystery Meat."

The title of the episode is stated by Skulker.

Running Gags: 1) Skulker being sent away due to Tucker's PDA just when he is about to attack Danny. 2) The Ghost Gabber saying, "Fear me." 3) Skulker getting attacked by an animal

It is revealed that there is a release button on the Fenton Thermos.
